Invisible cloak closer to reality

In a first, scientists made an object disappear by using a composite material that can enhance an object’s surface properties, an advance that may lead to practical invisibility cloaks. Researchers at Queen Mary University of London School of Electronic Engineering and Computer Science, presented a cloaking device that allows curved surfaces to appear flat to electromagnetic waves. The design is based on transformation optics, a concept behind the idea of the invisibility cloak.
